Building MFEM dependency frozen due to Cmake consuming too much RAM #127

Closed axla-io closed 2 years ago

axla-io commented 2 years ago

Issue

Cmake creates too many parallel processes when installing MFEM. They consume all available RAM and causes the program to freeze.

Affected

I encountered this problem when installing libROM with MFEM dependency on two different laptops with 8Gb RAM.

Fix

Change the -j flag to -j8, or some other resonable finite number, in the cmake compilation of MFEM in /scripts/setup.sh
